3D Printing - Fundamentals
Why does the SLA process require supports for some 3D models during printing?
ATo cool the resin faster after curing
BTo speed up the laser scanning process
CTo hold overhanging parts in place while resin cures
DTo reduce the amount of resin used
Step-by-Step Solution
Solution:
  1. Step 1: Understand the role of supports in SLA printing

    Supports prevent overhanging or delicate parts from sagging or falling during curing.
  2. Step 2: Eliminate incorrect reasons

    Supports do not affect laser speed, cooling, or resin volume directly.
  3. Final Answer:

    To hold overhanging parts in place while resin cures -> Option C
  4. Quick Check:

    Supports stabilize parts during curing [OK]
Quick Trick: Supports prevent sagging of overhangs [OK]
Common Mistakes:
MISTAKES
  • Thinking supports speed printing
  • Assuming supports cool resin
  • Believing supports save resin
